LINDBLAD-APPROACH TO NONLINEAR JAYNES-CUMMINGS-DYNAMICS OF A TRAPPED ION

The Lindblad approach to open quantum systems is introduced to study t he dynamics of a single trapped ion prepared in nonclassical motional states and subjected to continuous measurement of its internal populat ion. This results in an inhibition of the dynamics similar to the one occurring in the quantum Zeno effect. In particular, modifications to the Jaynes-Cummings collapses and revivals arising from an initial coh erent state of motion in various regimes of interaction with the drivi ng laser; are dealt with in detail.
